Reliable analysis of settling errors in SC integrators-application to the design of high-speed /spl Sigma//spl Delta/ modulators
(Institute of Electrical and Electronics Engineers, 2000)
This paper presents a detailed study on the transient response of SC integrators which takes into account the effects of amplifier finite gain-bandwidth product, slew-rate, and parasitic capacitances. Unlike previous models, ...

Design of a compact and low-power TDC for an array of SiPM's in 110nm CIS technology
(Institute of Electrical and Electronics Engineers, 2017)
Silicon photomultipliers (SiPMs) are meant to substitute photomultiplier tubes in high-energy physics detectors and nuclear medicine. This is because of their -to name a few interesting properties- compactness, lower bias ...

Geometrically-constrained, parasitic-aware synthesis of analog ICs
(The International Society for Optical Engineering - SPIE, 2005)
In order to speed up the design process of analog ICs, iterations between different design stages should be avoided as much as possible. More specifically, spins between electrical and physical synthesis should be reduced ...
